CHICAGO -- Javier Baez now has one week in the big leagues, and it's been a learning experience.

"As expected, there's been some high highs and some lows," general manager Jed Hoyer said Wednesday of the infielder, ranked No. 2 on MLB.com's list of top 20 Cubs prospects. "He'll probably settle somewhere in the middle."

Baez was promoted last Tuesday in Colorado, and hit three home runs in his first three games, including a game-winning homer in the 12th inning of his debut on Aug. 5, and two homers two days later. In Wednesday's 4-2 victory over the Brewers, Baez hit his first homer at Wrigley Field and went 2-for-4, raising his batting average to .268 with 13 strikeouts in 41 at-bats.

"This is why he's here, so he can play every day and have those experiences," Hoyer said. "The way he is as a player, he'll learn from those things. You can see the talent and see the things he's done well."

The other Cubs players were eager for Baez to be promoted, and Hoyer said he was happy to see them embrace the 21-year-old second baseman.

"It should be a good 45 days or so for him," Hoyer said.

There are no plans to have Baez play at shortstop, which is where he has primarily played in the Minor Leagues.

"I think once Javy gets comfortable there, he'll be a really elite second baseman," Hoyer said. "We know he can play shortstop."
